Bumper for brooms



Patented Apr. 1, 1930 FATE ALFRED D. SUND, OF SANTA ROSA, CALIFORNIA BUMPER FOR BROOMS Application filed .Tune 27,

The invention forming the subject matter of this application relates to bumpers for broo'ms, and particularly to the type of bumpers disclosed in my co-pending application,

Serial No. 256,557, filed February 24,-, 1928.

The bumper leg for brooms disclosed in the aforesaid co-pending application is particularly adapted to be secured to the broom handle. The function of the aforesaid bumper leg is to provide a member protrud-' ing at an angle to the handle of the broom, the bumping of which on the floor will efficiently effect the cleaning of the broom bristles from the dirt and dust accumulated thereon.

The primary object of the present invention is the provision of a bumper which may be readily secured to the broom handle and to the broom in such a manner as to secure the broom handle to the broom, and at the same time'serve as a bumper so that the stresses exerted upon the broom handle and the broom, while the'bumper is used, affect both the broom handle and the broom without causing any injury or deterioration to the usual fastening means of the broom handle.

Another object of the invention is the pro vision of a bumper which may be readily secured to the broom handle or to the broom or to both, and which may be also employed for securing the broom handle to the broom, thereby protecting the usual securing means, such as threads at the end of the broom handle, from rapid deterioration.

A further object of the invention is the provision of a bumper for brooms which may be so secured to the broom handle and the broom as to hold the broom handle in place,

40 thereby allowing the connection of a handle to a broom after the threads of other securing means therein are entirely worn out. In this event, the broom handle is held in place by my particular bumper which, at the same time, provides a bumper leg extending at an angle to the broom handle for shaking accumulated dust and dirt from the broom bristles.

With the above mentioned objects and other objects in view, the invention consists 1928. Serial N0. 288,654.

in the novel construction and combination of parts, hereinafter described, illustratedin the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details in construction within the scope of the claims may be resorted to without departing from the spirit, or without sacrificing any, of the advantages, of the invention.

In the drawing:

Figure 1 is a side elevation of the broom and the broom handle, showing the bumper attached thereto, part ofthe broom handle being broken away; and

Figure 2 is a view shown partly in section, viewing the bumper and the broom from the direction of the arrow on the line 2 2 of Figure 1.

In carrying out my invention, I make use of a broom, denoted in its entirety by the numeral 5. The broom 5 comprises a handle 6, a bristle-carrying member 7, and bristles 8. The broom handle is secured into the bristle-carrying member 7 by means of a threaded end 9 thereon engaging an internally threaded hole 11 of said bristle-carrying member.

It is an every day occurence to find discarded bristlecarrying members 7 for the sole reason that the broom handle "6 cannot be secured thereinto on account of a worn out internal thread in the hole 11. lhe worn out In order to provide a more eflicient method e for shaking the bristles so as to reduce the wear upon the internal thread of the hole 11, and also for securing the handle 6'into the threaded hole 11 so as to reduce the wear of the threads thereat, I provide a bumper, de-

noted in its entirety by the numeral 12.

The bumper 12 comprises a bracket 13 ha'ving a bearing portion 14: thereon, the latter being substantially of semi-circular cross secton. A clamping member 16, also of substantially semi-circular cross section, is positioned opposite to the bearing member 14. A lug 17 extends from the lower end of the clamping member 16 toward the bracket 13, in which bracket is provided a slot 18, the lug 17 being slidable in the slot 18. In order to prevent the accidental withdrawal of the lug 17 from the slot 18, and also, to provide a bearing member on the opposite side of the bracket 13, an enlarged head 19 is formed at the extremity of the arcuate lug 17. The head 19 bears against the face of the bracket 13. The bracket is secured to the broom handle 6 by means of a screw 21 extending thru projections 22 which form part 7 of the bearing member 14 and the clamping member 16, respectively, and extend substantially in parallelism with each other. A nut 23, threaded upon the screw 21, is employed for pressing the project-ions 22 toward each other, thereby also pressing the enlarged head 19 against the face of the bracket 13, thus ous positions so as to extend to a difierent distance from the bracket 13.

It is to be noted that in my present bumper, the socket 26 and the extension 27 are disposed at an angle to each other, as shown in Figure 1, so that although the bracket 13 and the extension 24 protrude substantially at right angles to the broom handle 6, the bumper socket 26 is disposed in a vertical position when the broom is in the position shown in Figure 1.

Inside of the socket 26 is fixedly secured a rubber bumper 32, by means of a transversely disposed pin 33 extending and secured in the walls of the socket 26. In order to allow the securing of the bumper to the bristle-carrying member 7, ears 34 and 35 are provided, projecting laterally from the bumper. The car 34 extends from and forms part of the bearing member 14, while the other ear 35 extends from and forms part of the clamping member-16, as clearly shown in Figure 2. In each car 34 and 35 is a slot 36 having an enlarged portion 37, thruwhich the securing means may be inserted.

In some cases, the relative position of the broom handle 6 and the bristle-carrying member 7 is such that the bracket 13may assume a position where the ears 34 and 35 are positioned upon an edge of the bristle-carrying member 7. In that event, the cars 34 and 35 are bent around their longitudinal axis so that when the bumper is securely held, upon the handle 6, the ears 34 and 35, being in engagement with the edge of the bristlecarry ing member 7, n'event the rotating movement of the handle or the bumper relativcl to the bristle-Carr ing member 7.

In other cases where the threaded hole 11 is not disposed in close proximity to an edge of the bristle-carrying member 7, the securing of the bracket 13 to'the bristle-carrying memher 7 is accomplished by means of screws 38 secured in said bristle-carrying member. Although in the drawing, round head screws 38 are shown, it is apparent that any projection could be substituted for the round head screws 38, provider that each projection has a head of such size as to be insertable thru the enlarged portion 37 of the slot 36 and the projection itself being slidable in the slot 36.

r The securing of the bumper to the bristlecarrying member 7 and to the handle, and also the securing of the handle 6 to the bristlecarrylng member 7 1s accomplished as follows: The o ections or round head screws 38 are secured in the proper position so that 7 they form part of the bristle-carrying member; 7, the head of thescrews beingspaeed from said member. Then the broom handle 6 is screwed into the threaded hole '11, or in case the threaded hole 11 is worn out, the

handle 6 is merely inserted in the threaded ening the screw 21 and the nut 23,thc bracket 13 and the clamping member 16 firmly grip the handle, preventing the rotation thereof. It is evident that in this position, any rotation of the bracket 13 or the handle 6 relatively to the bristle-carrying member 7 is entirely obviated because of the engagement of the cars 34 and 35 with the screw 38, which prevents the rotating movement of the bumper 12. The socket 36 is secured and depends from the bracket 13 in the manner heretofore described.

It will be recognized that in place of the screw 38, any suitable, means may be provided on the ears 34 and 35 for engaging the bristle-carrying member 7 in such a manner as to prevent the relative movement of the I amount the handle 6 itself and function merely as a bumper as set forth in my co-pending application.

hen the bumper is secured to both the bristle-carrying member 7 and the broom handle 6, then the stress of the sweeping and the bumping is transmitted to the screws 38, thereby protecting the threads 11 and materially reducing the stress and the wear thereon. My invention results in a great of saving by allowing the use of brooms, in the bristle carrying member of which the threads are worn out, because the aforedescribed bumper 12 effectively secures the handle 6 to the broom itself regardless of the condition of the internal thread 11;

at the same time it also functions as an efficient bumper. 'Ihe bumper may be secured also to the broom itself without being secured to the handle, so that it may assume any desired position that appears to be convenient in any particular employment of a broom. The length of the bumper is readily adjustable, and the attachment thereof to anyused or new broom is easily accomplished.

I claim:

1. In a bumper leg for a broom, said broom having a handle thereon; an element secured to the broom head and extending at an angle to the broom head and to the broom handle; means on said element for clamping the broom handle and for obviating the movement of the handle relatively to the broom; and bumping means on the end of said element.

2.
